17 Claims invention relates to typewriting and like machinesand more particularly. to card clamping ,means.,forcylindrical platens employed in such...machines. V i

6- One of the main objects of my invention, generally statedis to :provide simple, comparatively inexpe $ive,-.and highly effective card clamping meansr:

A- -further; object-,of my invention is to provide 101 improved means whereby a plurality of independently controlled card clamps may be employed on a single platen to enable -a plurality 'ofcards to her-successively;,clamped in position along the platen without. disturbing those. already clamped 16 in place, and. in .orderto feed at one movement a pluralitwofrcardsarranged side-by side on the platenrand thereby-materially increase the speed at-.which the-cards maybe written.

Another objectof my invention is to so constructand-arrangegthe'parts that by reversing the platen. end-for-end, .the cardholding devicesmaybeconditioned so as to change the direction? of feed of--the cards; a, back feed of the. cards being effected in one case and a front zo' feediin theother;

A-still further. object .of the invention is to so construct and arrange the parts that independentlysoperable finger pieces that control the opening of the clamps are so situated that ready access thereto may be had by the operator when the platen is in acard receiving position, there by facilitating the speedy clamping of the cards in place or the withdrawal thereof from the platen whether the cards are being back fed or front fed.

Still another object of my invention is to so construct the card clamping and controlling means that they may be supplied in separate units, andone or more units may be readily applied to a platen in accordance with the requirements of the user.-

To the above and other ends which will hereinafter appear myinvention consists in the features-oiconstruction, arrangements of parts and 4.5 combinations ofdevices set forth in the following; description and particularly pointed out in the appended claims.

I n.the accompanying drawings wherein like reference characters indicate corresponding parts in the different views- Fig.1 is a, front view of the platen, with parts in -.se c tion,- equipped with card clamping devices of.z ny invention.

Fig. 6 is a sectional view corresponding to Fig. 2 but showing the platen reversed end-for-end for effecting a front feed of a card.

In the present instance I have shown my invention embodied in a platen of a No. 6 Remington Noiseless machine although it is also applicable to the platens of a No. 8 Remington machine, and may in fact be employed in platens of typewriting and like machines generally, wherever found available.

The cylindrical platen, which is designated as a whole by the reference numeral 10, in the present instance comprises an inner metal shell 11 surrounded by a rubber sheathor covering 12. The platen is apertured at 13 throughout the length thereof to receive several series of pins 14. These pins of each separate series are riveted to and project from a sheet metal support or carrier 15 that is preferably angular in cross section to add to the rigidity of the carrier. Each carrier 15 is provided at the ends thereof with ears 16 and 1'7 that are formed integral with the base portion of the carrier to which the pins 14 are secured. The ears 16 and 1'. are pierced to receive a pivot rod 18 that is supported in openings in blocks or hangers 19 riveted at 20 to the inner metal shell 11 of the platen and projecting inward therefrom.

Surrounding each pin 14 is a coiled expansion spring 21 that bears at one end against a carrier 15, and at its opposite end bears against a perforated metal bar 22 through the openings in which the pins extend, it being understood that a separate bar 22 is provided for each clamping unit. Each bar 22 is interposed between the outer ends of the associated coiled expansion springs 21 and the inner side of the metal shell 11 and has a bodily movement with the companion pins during the rocking of their carrier 15 around its pivot rod 18 from the Fig. 3 to the Fig. 2 position and vice versa. It will be understood that each plate or bar 22 constitutes an abutment against which the outer ends of the associated no ably securedj'to the outer ends of the companion series of pins. In practice it may only be necessary to provide a screw 24 for every other pin of a series, as indicated in Fig. 1. It is desirable,

however, to employ a comparatively close ar-" rangement of the pins 14 in orderthat they may constitute an effective abutment against which an edge of a card 26 may bear and be squaredas indicated in Figs. 2 and 3, even when a very-narrow card is employed.

The effective force of each series of springs 21 is exerted to normally maintain the companion parts in the Fig. 3 position with the clamping bar pressed against the outer cut-away portion of the platen, indicated at 27,-and to firmly hold the leading edge of a card against the platen and causej'the'eard to be fed with the platen either ,wi tha backfee'd, as'indicated in Fig. 2, or a front feedasindlcate d'in Fig. 6. It will be understood tliatthe clamping bars when in the effective position'are maintained substantially flush with the outer ,surface, of the platen, so that they cannot engage :the rroatend 28 of the paper apron 29 -"as,tliiec'arclclamps.in a back feed pass said front end 28in the movement of the clamps in a clockwise iirection. as the parts appear in Fig. 6.

.In-order to .effect a release of each card clamp,

I have provided, in the present instance, a separate;independently operable finger piece 30 for eacnunit, and. each finger piece in the normal position of the associated parts'represented in Fig.3, has its outer contact face substantially flush-with the surface of the platen. Each finger piece moves in opening 31 provided in the platen and is located outside of the field of the associatedcard clamp, or. any of them, being preferablyofi-set to the left of the associated card clamp, as indicated in Fig. l. The relative arrangement of the parts is such that access may be readily had to a finger piece 30, or each of them, when the platen is in the card receiving position, whether .the card be back fed or front fed, as

indicated in Figs. 2 and 6 respectively. Each finger piece is connected to a stem or plunger 32 pivoted at its lower end at 33 to a control lever 34.

I prefer to employ a leaf spring 35 riveted at 36 to each stem 32, the free end of said spring overlapping the-associated lever 34 and the pivot 33 thereof, in order to effectively maintain the pivotal connection between the key stem and lever, yet permitting a ready disconnection and reconnection to be effected between these parts when desired.

rier l5. This pivotal connection at 38 is on the opposite side of the pivot rod 18 from that where the pins 14 are located. It will be understood therefore that a depression of a finger piece 30 to the Fig. 2 or Fig. 6 position is effective to rock thecornpanion lever 34 and effect a pivotal movement of the associated carrier 15 around its pivotrod 18, thereby swinging the pins 14 carried thereby from the Fig. 1 to the Fig. 2 or Fig. 6 position against the force of the springs 21 and thus release the associated card clamp 25.

The parts of each clamp constitute a single unit, and as many of these units may be employed on a single platen as the character of the work requires. I prefer to employ a plurality of independent carriers 15, say for example three, all mounted on the single pivot rod 18 and each provided with its own individual release key 30 and associated parts, whereby any one cardclamp may be released independently of the others. In this manner a plurality of cards may be successively clamped side-by-side on the platen and after a card is clamped in position by one card clamp it is unnecessary to release such clamped card in order to clamp a second and a third card in place. The card clamps are preferably arranged in alignment longitudinally of the platen, as indicated in Figs. 1 and 4, and as hereinbefore indicated as many independently operable card clamps may be employed as are found necessary or the length of the platen employed will permit.

It will be noted that in each instance the finger piece by which a card c controlled'is.

off-set laterally from the field of its card clamp and from the other card clamps as well and does not interfere with the ready insertion of a card in'place in any clamp,ja'nd'all of the finger pieces are readily accessible to the operator when the platen is in a card receiving position, indicated in Figs. 2 and 6. The off-set arrangement of the finger pieces in the face of the platen is clearly indicated in Figs. 1 and 4.

In'assembling the parts, each carrier 15', with V the parts carried thereby, is introduced into the platen, it being understood that one or "both of the usual platen heads 40 is removed at this time. '1 10 The pins=14 on each carrier are introduced-from inside of the platen through the aperture 13 and the associated clamping plate 25 is then secured to the pins,- or to some of them, by the screws 24.

The pivot rod 18 is introduced endwise'through the openirigs' in the hangers and bearing-openings in the ears 16 and 17 of the carrier to pivotally support it in place. Theassociated finger piece'30'which has previously been inserted in' the platen is then connected at its pivot 33 to the companion control lever 34. Each' unit is assembled in the same general manner.

The usual feed rollers 41 extend through openings in the paper apron 29 and cooperate with the cards 26 as they are fed by the platen and card clamps past said feed rollers, whether the cards be back fed, as indicated in Figs. 2 and '3, or be front fed, as indicated in Fig. 6.

Various changes may be made in the construction, and certain features thereof may be employed without others, without departing from my invention as it is defined in the accompanying claims.
